Strains of Aeromonas salmonicida ssp. salmonicida lacking pigment production were isolated from brown trout Salmo trutta m. lacustris and sea trout S. trutta m. trutta cultivated in fresh water in southern Finland. The bacteria isolated showed only minor deviations in biochemical characteristics compared to 2 strains of A. salmonicida spp. salmonicida and the type strain of A. salmonicida spp. salmonicida. Several characters differed when compared to the type strain of A. salmonicida ssp. achromogenes. In challenge experiments, the strain tested was highly pathogenic to rainbow trout Oncorhynchus mykiss.
